Hi,
We would like to let you know that our spamtest feature is exclusively available as part of our Enterprise license. However, we have recently discovered a bug that made this feature accessible in the Essential version, which you have benefited from until now.
We want to inform you that we have fixed this bug and if you would like to continue utilizing the spamtest feature, we kindly invite you to upgrade your license to the Enterprise level.
Thank you for your cooperation and understanding.
